概述Overview上海帕特泵业制造有限公司产生的螺杆泵是一种单螺杆输运泵，它的主要工作部件是偏心螺旋体的螺杆（称转子）和内表面呈双线螺旋面的螺杆衬套（称定子）。其工作原理是当电动机带动泵轴转动时，螺杆一方面绕本身的轴线旋转，另一方面它又沿衬套内表面滚动，于是形成泵的密封腔室。螺杆每转一周，密封腔中的液体向前推进一个螺距。随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。Screw pump is a single-screw transfer pump. Its main working parts include the screw of eccentric helicoids(called rotor)and the screw bush with a double-line helicoids on its surface(called stator). Its working principle goes like this: when the electromotor drives the pump shaft to rotate, the screw rotates around its own axes one hand and rolls along the inner surface of the bush on the other, thus forming a seal cavity in the pump. When the screw rotates a cycle, the liquid in the seal cavity will advance a screw pitch forward. With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally. 螺杆泵是一种新型的输送液体的机械，具有结构简单、工作安全可靠、使用维修方便、出液连续均匀、压力稳定等优点。我单位生产的浓浆泵凡接触物料的金属零件均选用优质不锈耐酸钢制作，轴材料2cr13衬筒采用无毒无味的橡胶、工作温度可达100℃，可用于输送食品浆料和粘度10000泊斯卡·秒含有固体颗粒或胶块的溶液浆，悬浮液的腐蚀性介质。广泛用于食品、冶金、建筑、制药、化工等工业部门。Screw pump is a new type of machinery for the liquid transfer. It boasts such advantages as simple structure, safe and reliable operation, easy operation and maintenance, continuous and uniform liquid discharge and stable pressure. The metal parts contacting materials of our underflow pump all adopt top-grade stainless acid-proof steel; the shaft material is 2cr13;the bush adopts nontoxic rubber with no peculiar smell; its working temperature can reach up to 100℃. It can be used for the transfer of corrosive media like foodstuff slurry, solution or suspension containing solid grains or rubber blocks with a viscosity of 10000Pa·s. It is widely applied in such industrial sectors as food, metallurgy, construction, pharmacy and chemical industry.
